TUFT-YARN-OARRYING SPOOLS OF LOOMS FOR WEAVING TUFTED FABRICS.

Specification of Letters Patent.

Patented Oct. 10, 1911.

Application filed December 7, 1908. Serial No. 466,333.

To all whom ti may concern:

Be it known that I, THOMAS CooPER', a subject of the King of GreatBritain, residing at Farfield, Kidderminster, England, have inventedcertain new and useful Improvements in and in Connection with theTuft-Yarn-Carrying Spools of Looms for Weaving Tufted Fabrics, of whichthe following is a specification.

Hy invention relates to tuft-yarn-carrying spools of looms for weavingtufted fabrics wherein, as in looms of more than the usual width two ormore of the said spools are arranged end to end or in line in each spoolcarrying or tube frame, and my invention consists of the improvementshereinafter described in and in connection with the said spools, theobject of said improvements being to insure the rotation in unison ofthe two or more spools in each spool-carrying or tube frame when thetuft yarn is drawn from off the spools in the weaving of the tuftedfabric.

The essential feature of my invention consists in so constructing andconnecting the adjacent ends of the spools in line that a very efficientinterlocking engagement or coupling together of the two or more spoolsin each tube frame is effected.

I will describe my invention in connection with the accompanying drawingFigure l of which represents in front elevation a spoolcarrying or tubeframe in which three spools in line, interlocked or coupled togetheraccording to my invention are employed parts of the spools and carryingframe being broken away. Fig. 2 represents in longitudinal section theadjacent or coupled ends of two of the spools, showing the standard orsupporting bearing on the tube frame in which the connecting spindle ofthe spools rotates when the tuft yarn is drawn therefrom. Fig. 3 is alongitudinal sectional view showing the ends of the spools separated.Fig. 4L is an end elevation of the left hand spool shown in Figs. 2 and3. Fig. 5 is a transverse section taken on the line 55 of Fig. 4:. Fig.6 is an end elevation of the right hand spool. Fig. 7 is a sideelevation of a supporting bracket. Figs. 8 and 9 are end and sideelevations of twomodified forms of spindle. Fig. 10 is a longitudinalsectional view of a further modification of the invention. Fig. 11 is aside elevation of the spindle shown in Fig. 10. Fig. 12 is a crosssectional view of Fig. 11, and Fig. 13

is a detail view of oneof the locking plates employed in connection withsaid spindle.

The same letters of reference indicate the same parts in the severalfigures of the drawing.

According to the arrangement of my invention illustrated in Figs. 1 to 7inclusive I provide one end of the central spool a, with a fixedprojecting spindle b, and the adjacent end of the left-hand spool a witha tubular socket 0 the spindle 7) having a length proper to pass throughthe standard or supporting bracket or bearing (Z on the tube frame 6 andto take into and fit the socket 0. To provide for an interlockingengagement between the spindle b and socket 0 such as will prevent therotary movement of one spool with respect to the other the spindle b isprovided with a cross pin 6 (see Figs. 3 and 6) the projecting ends ofwhich engage with notches or grooves 0 0 (best seen in Figs. 4 and 5) inthe outer end of the tubular socket c the engagement of the cross pin 72with the notches 0 0 being illustrated in Fig. 2. The connection betweenthe mutually adjacent ends of the central spool a and the right handspool a is eifected in a similar manner. By the connection or couplingof the adjacent ends of the spools in the manner hereinbefore describedand illustrated the rotation of each series of tuft yarn carrying spoolsas one is insured.

The spindle b of the spool a is engaged with and disengaged from thesocket 0 of the adjacent spool a by employing a bracket or bearing dwith a slotted sliding front bar 03 which when in its lowered position(seen in Fig. 7 permits the spindle Z) to be passed into or drawn out ofthe bracket or bearing d. The spindle b is passed into the socket 0 whenthe axes of the two spools are inclined to each other the said spindle bentering into the socket c as the two spools are brought gradually intoline.

I wish it to be understood that I do not limit myself to the particulararrangement hereinbefore described and represented for effecting thecoupling of the adjacent ends of the spools as the same may be effectedin various ways. For example, instead of providing the fixed spindle bwith a cross pin Z2 and the outer end or face of the socket c with crossgrooves or notches 0 the part b of the spindle which takes into thesocket may have any preferred cross sectional contour other thancircular as is illustrated in Figs. 8 and 9, Fig. 8 showing a spindlewith an elliptical end and Fig. 9 showing a spin dle with a square endthe socket 0 having internally a corresponding figure in cross section.Or the ends of both spools may have sockets and a movable spindle be employed therein so as to effect a coupling of the two spools together.

Figs. 10, 11 12 and 13 illustrate an arrangement where both spools havesocketed or tubular ends and a loose or movable spindle is employed.

From an examination of Figs. 11 and 12 it will be seen that the spindle6* is of pinion section excepting at one end. The spools a and a areeach provided with an end disk or plate a having an opening shaped tofit the pinion-like spindle Z)", one of the disks or plates a beingshown separately in Fig. 13. The spindle b is passed through one of thedisks a before the said disk is secured to the spool, the unnotched endof the spindle being situated on the inner side of the disk. A spring fis arranged in the socket of the spool a which carries the spindle b topress the spindle outward. An opening b in the spindle 6* permits a toolto be employed for withdrawing the spindle from the adjacent spoolsocket.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is In a loom, the combination of a pair ofspools arranged end to end; a member connecting the ends of the spoolsand having its own ends locked against rotation within the spools,whereby the spools are caused to rotate in unison; and a supportcomprising a member formed with a seat for the reception of theconnecting member, and a slide arranged for movement across said seat toretain said connecting member therein.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

THOMAS COOPER.
